Adding nitrates without adding Ca, Mg or K

The only other compound that is a likely candidate would be sodium
nitrate. The others are poisonous, expensive, or unavailable.
If this is for a planted tank, what's wrong with readily available
potassium nitrate ? Usually a planted tank needs more potassium than
nitrate, so you use KNO3 to supply as much nitrate as needed and add
more KCl to get the K up to target.
I add some KH2PO4 and my K is nearly at 60 ppm.
Perhaps, shall I reduce TMG and Profito supplies
but how be sure that traces are sufficient ?
Thanks again !
